shown in Figures 44, 45, and 46 is a very useful shape for a 

 snaffle bit. 



The bit that has 

 the least painful in- 

 fluence on the 

 horse's mouth i s 

 the rubber-covered 

 bar bit. Theoret- 

 ically, this is the 

 ideal bit. 



Mechanically any 

 bit not having lev- 

 er action acts as 

 shown in the accom- 

 panying plates. 



I n Figures 4 5 

 and 46 AB repre- 

 sents, graphically, 

 a force, ^ |a c t i n g 

 through a pull on 

 the reins fastened 

 to a bar or snaffle 

 bit, on the horse's 

 jaw at A. Resolv- 

 ing this force into 

 its two components, 

 AE at right angles 

 to the horse's jaw 

 and AD parallel to 

 it, AE will then 

 represent the actual 

 useful restraining 



force and AD the wasteful force, operating merely to raise the 



horse's head.
